I’m Hashir, a Software Engineer experienced in Golang and Angular, building REST APIs and backend services using Gin, Gorilla Mux, and Uber Fx. I work with JWT authentication, RBAC, Clean Architecture, CQRS, and the Repository pattern. I handle data using MongoDB (aggregation pipelines), PostgreSQL, MySQL, and SQL Server. On the frontend, I develop Angular applications with module-based routing, standalone components, lazy loading, and dynamic themes. I also work with Docker, Linux, and AWS to deliver production-ready solutions.
